Issues With Gitlab Webhooks Causing Builds to Not Execute
Incident Report for CircleCI
Resolved
The issue has been resolved.

It should be noted that customers that attempted to trigger a build during the outage may need to navigate to the webhook settings in the GitLab UI, then reactivate the webhook before being able to trigger a build again. If you continue to see this issue after reactivating your webhook, you must remove it completely and recreate it.
